I haven't been following this thread, so sorry if this has already come
up...

I'm not familiar with NetworkManager, but there's a good chance that
it's using the normal dhclient under the hood to deal with dhcp. If so,
then you should be able to edit your /etc/dhclient.conf a bit and solve
this. The trick here would be the 'supersede' setting. I do this on my
laptop like this:

supersede domain-name-servers 127.0.0.1;

This is for my local, caching-only name server. You may list multiple
servers, etc. You can also use 'supersede' with other options as well,
if you don't like the domain name dhcp hands out, for instance.

I hope this is on target...
